Abstract

The present application is applicable to the technical field of medical imaging, and provides a method and device for generating an AIF curve, which can improve the accuracy of the AIF curve. The method comprises: before injecting the contrast agent in the target area, respectively exciting and collecting reference signals of NS slices in the target area, where NS>1; AIF aliasing signal; use the reference information to reconstruct the AIF aliasing signal to obtain the AIF reconstruction image of each slice; perform concentration conversion processing on the AIF reconstruction image of each slice to obtain the first AIF curve of each slice , the first AIF curve is the change curve of the concentration of the contrast agent over time in the corresponding slice; the obtained NS first AIF curves are averaged to obtain the second AIF curve, and the second AIF curve is In the area, the concentration of contrast agent changes with time.

Description

technical field [0001] The present invention relates to the technical field of medical imaging, in particular to a method and device for generating an arterial input function (Arterial input function, AIF) curve. Background technique [0002] Magnetic Resonance Imaging (MRI) technology is the core technology in medical imaging. Using magnetic resonance imaging technology to image the perfusion process of blood entering the tissue (also called perfusion imaging), the obtained perfusion images allow people to observe the perfusion of blood after entering the tissue, and provide a reference for evaluating the health of the tissue. In MRI, quantitative perfusion can often reflect tissue perfusion more objectively. For example, quantitative perfusion can quantify myocardial blood flow (Myocardial Bloocl Flow, MBF), cerebral blood flow (Cerebral Blood Flow, CBF), cerebral blood volume (Cerebral Blood Volume, CBV), etc. [0003] During the quantitative perfusion process, it is us...
